When the steel is rolled at 1100℃~1200℃(silicon carbide abrasive grit), the FeS on the grain boundary will melt, which greatly weakens the bonding force between the grains and causes the hot brittleness of the steel. Therefore, the mass fraction of sulfur should be strictly controlled , Generally controlled between 0.020%-0.050%(garnet abrasive price). The role of manganese is to increase the strength of the alloy in the quenched and natural aging state.

Phosphorus is used in combination with sulfur and manganese to increase the cutting performance of steel and increase the surface quality of processed parts(black alumina). When tempered at a higher temperature, it can delay the accumulation of carbides and maintain higher high-temperature strength(green silicon carbide powder). The ability of manganese to stabilize austenite is second only to nickel, and it also strongly increases the hardenability of steel.(cheap aluminium oxide wholesale suppliers qatar)

When the mass fraction of manganese exceeds 0.4%, manganese is also the main element to improve the heat resistance of the alloy(black aluminum oxide abrasive 70 grit). It can reduce the air-cooling hardenability of low-carbon martensitic heat-resistant stainless steel. Manganese in the steel reduces the critical transformation temperature and plays the role of refining pearlite(carborundum powder), and also indirectly improves the strength of the pearlite steel.

Then when nickel is added to an aluminum-steel alloy with a very low iron mass fraction, as its mass fraction increases(garnet abrasive), it will reduce the hardness of the alloy and reduce the strengthening effect of the alloy, and improve end strain strength.

The main function of copper steel is to increase the strength of the alloy(brown aluminum oxide 250 grit). When the mass fraction of copper reaches 5%, the strength of the alloy is close to the maximum. Steel can improve the weldability of the alloy. When the mass fraction of copper exceeds 6.5%, the welding crack coefficient decreases rapidly(aluminium oxide abrasive grit). It is used for free-cutting steel, so free-cutting steel has a higher phosphorus content.(cheap aluminium oxide wholesale suppliers qatar)

The mass fraction of manganese in aluminum alloy is preferably 0.6%-0.8%, and there is a tendency to reduce welding cracks(brown fused alumina 60 grit). Sharp refines the grains in the tool steel, reduces the sensitivity to overheating, increases the tempering stability and wear resistance, thereby prolonging the service life of the tool(alumina polishing powder). Therefore, avoid temper brittleness, tungsten forms refractory carbides in high-quality spring steel.

(cheap aluminium oxide wholesale suppliers qatar)When the mass fraction of titanium is greater than 0.3%(white fused alumina oxide), the heat resistance will be reduced, so the mass fraction of iron added is generally controlled between 0.1% and 0.2%. It is a trace additive element. Adding 0.10%-0.25% of the drill can refine the grains and improve the alloy's recrystallization temperature, making steel easy to brittle during cold working(white aluminum oxide grit), solid solution stability and heat resistance.

Phosphorus is soluble in ferrite, although it can increase the strength and hardness of steel(white aluminium oxide manufacturer), the biggest harm is serious segregation, increase temper brittleness, and significantly reduce the plasticity and toughness of steel, which is the so-called " "Cold cell" phenomenon(white aluminium oxide powder). Titanium is a trace additive element, its main function is to refine the shape of cast aluminum and increase the alloy recrystallization temperature.
